convex, with an indentation in the medial line of the posterior 

 region : mandibles strong, conical, armed with teeth on the inner 

 surface, and inclined towards the sternum, which is heart-shaped : 

 maxillae inclined towards the lip, which is semicircular and pro- 

 minent at the extremity : first and fourth pairs of legs the longest 

 and equal in length, third pair the shortest : these parts, with the 

 palpi, are brown, the sternum and lip being the darkest, and the 

 legs much the lighest coloured. The radial joint of the palpi is 

 much larger than the cubital, and projects from its extremity, in 

 front, a pointed apophysis which is curved outwards ; the digital 

 joint is somewhat oval, with a bold protuberance at the upper 

 part, which is deeply indented on the outer side ; it is convex and 

 hairy externally, concave within, comprising the palpal organs ; 

 they are highly developed, complicated in structure, and of a 

 reddish brown colour. Abdomen oviform, convex above, pro- 

 jecting over the base of the cephalo-thorax ; it is thinly covered 

 with hairs, glossy and brownish black. Plates of the spiracles 

 brown. 



In June 1841 this spider was captured among fragments of 

 rock in a wood near Hendre House.

The legs and palpi are provided with hairs, and are red with 

 a tinge of brown. First pair of legs rather the longest, then 

 the fourth, third pair the shortest. Cephalo-thorax oval, glossy, 

 convex, with a small longitudinal indentation immediately be- 

 hind each lateral pair of eyes, and a slight depression in the me- 

 dial line of the posterior region : mandibles powerful, conical, 

 convex in front, near the base, divergent at the extremities, armed 

 with teeth on the inner surface, and inclined towards the ster- 

 num, which is broad and heart-shaped : maxillse strong, enlarged 

 where the palpi are inserted, and inclined towards the lip, which 

 is semicircular and prominent at the extremity : these parts are 

 brown-black, the maxillse, which are the palest, and the man- 

 dibles having a tinge of red. Anterior eyes of the trapezoid 

 much the smallest of the eight ; eyes of each lateral pair con- 

 tiguous and seated on a prominence. The cubital and radial
